We are replacing the alm bearings with wood ones. Our parts man says there are 2 types, 1 that clamp on like 20 series (one on bottom one on top), other that clamp one front, one rear, ( the seam between blocks will be facing up and down). Any experience with these 2 types, we are not real sure how the 2nd type will fit.
